2 claims.

This invention relates to tubular lantern constructions and has for itsobject to provide novel bracing means between the font and one of thelantern tubes and between the dome and both of the lantern tubes so asto increase the strength, sturdiness and rigidity of the entire lanternconstruction.

Another object of this invention is to combine the novel bracing meanswith the lantern bale suspension and the globe lifting means.

These and other objects and attendant advantages will become morereadily apparent from the detailed description of the invention whichfollows, reference being had to the accompanying drawing in which YFigure 1 is a front elevation of a tubular lantern embodying my novelbracing means.

Figure 2 is a detail sectional View taken Yon the line 25u-2x of Figure1 illustrating in a bottom plan View one of the bracing members and itsconnection between the tube and the dome of the lantern.

Figure 3 is a detail side elevation of the dome of the lantern.

Figure 4 is a detail vertical sectional view of the brace between one ofthe tubes of the lantern and the font thereof, the section being takenon the line lla-4:1: of Figure 1.

Figure 5 is a horizontal sectional View taken on the line tim-5.1: ofFigure 4 illustrating a top plan view of the brace between one of thetubes and the font of the lantern.

In the several figures of the drawing like reference numerals indicatelike parts.

- The tubular lantern construction forming the subject matter of mypresent invention comprises the font I including its burner 2 and thetubes 3, 3 extending from the burner over the font and up to the dome 4.A lantern globe 5 is supported on a base 6 which surrounds the burnerand is pivotally connected to the crank 1 so that on the swinging of thecrank by means of its handle 8 in its movement from the full lineposition to the dotted line position in Figure 4, the base 6 with thelantern globe is raised above the burner 2 to permit the lightingthereof.

One end of the crank is pivotally supported on one of the tubes 3 of thelantern on one side of the globe 5Y and the other end is pivotallysupported in the bearing 9 of the bracing member I0 which is fastened tothe other of the tubes 3 of the lantern and the top of the font Ithereof as will hereinafter appear. The bracing member I0 comprises 'asubstantially vertical member provided with outwardly spreading and an.-

(Cl. v2340--27 gularly extending feet II, II which straddle thehorizontal portion of the tube 3 as illustrated in Figure 4. The bottomof the feet of the bracing member are soldered or otherwise fastened tothe top of the font I so as to locate this member between the tube 3 andthe globe supporting base 6 and support the crank I to permit the handle8 thereof to swing between the globe 5 and tube 3.

The upper portion of the bracing member has a pair of flanges I2, I2bent outwardly therefrom. These flanges engagevthe sides of the' tube 3and are soldered or otherwise suitably fastened thereto. The bracingmember I0 thus braces the tube 3 on the font I from opposite sides andrigidly anchors the tube to the font in addition to the directattachment of its horizontal portion to the font. `The bracing member I0in bracing one of the tubes 3 thus serves to keep both of the tubes frombeing twisted off the font and its burner when lateral pressure isapplied to the tubes or the dome supported by them.

'I'he bearing `9 is formed in the side of the bracing member and holdsthe crank rotatablyv supported therein. To one side of the bearing isprovided the locking flange I4 which projects upwardly from the bracingmember and is rounded toward the tube 3 to provide an elongatedhorizontally extending latch over which the shank of the handle 8 mustbe forced when moving the handle from the full line to the dottedlineposition in Figure 4 for the purpose of raising the lantern globe. Therounded latch I4 extends angularly from the bearing 9 so that itsincreased thickness and elongated round surface permits the shank of thehandle 8 to gradually and easily slide thereover without causing anyappreciable wear von either the latch or the shank.

The brace between the tubes 3 and the dome 4 of the lantern is providedin the formation and attachment of the eyes it, I6 which support thebail I1 of the lantern. These eyes are made up in the form of a closedwire loop which are soldered to the tubes 3 so as to project angularlytherefrom. The parallel free ends of these loops project horizontallythru the tubes 3 into the dome 4 at the bottom thereof and are bent up-Y wardly on the inside thereof to hold the ends anchored thereto eitherwith or without further fastening means. In this way the bottom of thedome is anchored Vto the tubes 3, 3 intermediate PATENT OFFICE;

the ends thereof and keeps the dome from turnf The bracing of one of thetubes on the font and the bracing between the dome and both of thetubes, as above described, secures for the lantern constructionincreased rigidity and ruggedness which keeps the lantern in perfectworking condition 'for a much longer period than has heretofore beenpossible with this type of lantern.

I claim:

1. In a tubular lantern, the combination of the lantern frame comprisinga font `and air tubes secured thereto with the air tubes extendinghorizontally fromV the center portion of the font over the top thereofand then upwardly on the outside of the font, a lever mounted to swingfromV a substantially vertical position into a substantially horizontalposition for lifting the globe of the lantern between said air tubes, abi-furcated upright adapted to straddle the horizontal portion of one ofsaid air tubes and fastened to said font on opposite sides of said tubesuitably spaced therefrom to provide oppositely extending bracingmembers at the bottom of said upright, a pair of parallel verticallyarranged flanges formed on said upright and extending outwardlytherefrom so as to embrace and be fastened to oppo site sides of thevertical portion of said air tube at a point above the horizontalportion of said tube, a locking latch at the top of said upright andextending horizontally and substantially at right angles to said airtube and the upright so asto have said lever slide over said lockinglatch and engage under it substantially the full length thereof. Y

2.v In a tubular lantern the combination as set .forth in claim 1 inwhich said locking latch is formed by a substantially semi-cylindricalhorizontally extending ridge of gradually increasing width to provide alarge bearing surface for said handle to slide thereover and engagethereunder.
